What Feeds Beneath

While on an expedition at Todos Santos in south Baja California, Mexico, Alejandro Prieto was searching for big predators—such as marlins, sharks, or tuna—feeding on sardine bait balls, but instead he found this Hawaiian petrel feeding on crustaceans. “Luckily I was able to capture the moment it submerged its head to feed on the tiny food source,” Prieto writes.

The Power of Few

“The night before this photo, we tried all day to get a good photo of the endangered white rhino,” writes Stefane Berube, who captured this shot at the Ziwa Rhino Sanctuary in Uganda. “Skulking through the grass carefully, trying to stay 30 feet away to be safe, didn't provide me the photo I was hoping for. In the morning, however, I woke up to all three rhinos grazing in front of me.” Berube used a 50mm lens rather than a wide-angle lens or telephoto “because of its sharpness and similarity to how our eyes perceive depth in real life.”

Model Behavior

“I was in Kingston, Jamaica, volunteering at an HIV ward at Missionaries of the Poor and trying to learn how to do fashion photography,” writes Justin Anantawan. Working with amateur models, Anantawan spent the day near an abandoned fort at a beach in Port Royal, capturing this shot at sunset. “The shoot was very simple—I just bought some striped fabric and chiffon from a store in downtown Kingston, wrapped it around the men, and then let the scenery and ocean breeze do the rest of the work. The man on the right held up the chiffon, and I took around ten shots before I captured the fabric at the just the perfect moment.”

Bird Feeders

Abderazak Tissoukai was near Xingping in China’s Guanxi region when he captured this picture of a cormorant fisherman at sunset. “Xingping is definitely one the most beautiful places in China, with its scenic karst landscapes [and] traditional and genuine people,” he writes. Curious to learn more about the local practice of cormorant fishing—in which trained birds with snared throats capture fish they’re unable to swallow—Tissoukai took a high-speed train from Zhuhai to Xingping to shoot fishermen on the Li River. “I wanted a complete, iconic definition of cormorant fishing,” he writes.

Light in the Dark

Dancers pause during the Sinulog Festival in Cebu City, the capital of the Philippine province of Cebu. The large festival of cultural and religious pageantry honors the Santo NiƱo, or child Jesus, whose statue is held aloft here by a colorfully costumed “queen.”
